WP1: Requirements, Architecture and Process Definition
- Review of current best practice in integrated data centre ICT and environmental energy management
- Specification of requirements for GENiC power input requirements analysis
- GENiC management & draft system architecture
- Development of a process leading towards carbon neutral data centres.
Year 1 Achievements
- WP1 focused on the specification of requirements for the GENiC integrated energy and ICT load management platform, the requirements for renewable energy management to achieve a level of 80% renewable energy provision and the requirements for efficient reuse of ICT system heat in adjacent spaces to the data centre. An investigation into the most favourable renewable energy technologies that could be implemented in a given data centre was carried out. WP1 also most importantly saw the development of the architecture for an integrated energy and ICT load management platform and associated services.
Year 2 Achievements
- GENiC refined architecture specification complete!
The GENiC project has developed a high level architecture for an integrated design, management and control platform, targeting data centre wide optimisation of energy consumption by encapsulating monitoring and control of IT workload, data centre cooling, local power generation, energy storage, and waste heat recovery. The GENiC system integrates workload management, thermal management and power management by using a hierarchical control concept to coordinate the management sub-systems in an optimal manner with respect to the cost of energy consumption and environmental impact. A high level overview of the proposed GENiC system architecture is shown below, which consists of six functional groups known as GENiC Component Groups (GCGs):
- The Workload Management GCG is responsible for monitoring, analyzing, predicting, allocating, and actuating IT workload within the data centre.
- The Thermal Management GCG is responsible for monitoring the thermal environment and cooling systems in the data centre, predicting temperature profiles and cooling demand, and optimally coordinating and actuating the cooling systems.
- The Power & RES (Renewable energy Sources) Management GCG is responsible for monitoring and predicting power supply and demand, and for actuating the controllable RES systems connected to the data centre.
- The Supervision GCG includes the supervisory intelligence which provides optimal IT power demand, power supply, and thermal policies to the individual sub-systems based on monitoring data, predicted systems states, and actuation feedback.
- The Support Tools GCG includes a number of tools that provide decision support for data centre planners, system integrators, and data centre operators.
- The Integration Framework GCG provides the communication infrastructure that is used for all interactions be-tween the individual components of the GENiC system.
Each GCG is composed of a number of functional components known as GENiC Components (GCs). The core function of the GENiC sys-tem for continuous holistic data centre optimisation can be divided into four basic steps:
- Monitoring components within the management GCGs collect data about IT workload, thermal environment, cooling systems, power demand and (renewable) power supply.
- Prediction components within the management GCGs update their internal models and estimate future system states based on the collected monitoring data.
- Optimisation components determine optimal policies based on the collected monitoring data and calculated prediction data. These policies are provided to the man-agement GCGs.
- Actuation components within the individual management GCGs implement the policies provided by the optimisation components in the data centre and at the renewable energy sources facilities.
Year 3 Achievements
- Development of a process leading towards carbon neutral data centres which captures the experience the consortium gained in the GENiC project in how to develop a data centre powering and management system that can achieve sustained levels of powering by renewable energy sources through both careful IT and environmental management as well as novel approaches to use of renewable power in providing energy to data centres
